Okay then I'll give it a go
When you're choosing a geography topic, the first thing you need to think about is the availability and feasibility of the small-scale approach. Do you live in an area which has a certain accessible place that you could visit whenever you needed to without the need for a long drive (e.g. a park or a church etc)? Is there an area near school which you could visit regularly to collect data and make observations? Most likely you will do, so the first thing you should do is probably write up a list of geographically-important areas, places or buildings near you. This can include: parks, lakes, rivers, churches, shopping centres, schools, mountains/hills, forests, public transportation sites, an airport, a central business district, even things like deserts or fjords etc... Remember, geography studies why things where they are and the impacts the environment has on them and what impacts it has on the environment.
The next thing you need to do is you need to decide, out of your list of important geographical sites, decide whether you would prefer to do physical, human, or environmental (i.e.
mixed) geography. For example, originally my EE was based on physical geography (
"An investigation into the variations of infiltration rates in a green space in Brussels, Belgium"), then my supervisor told me that because it's in a park it would make sense to evaluate and conclude its interaction with the human environment surrounding the park, so my new title was
"An investigation into the variations of infiltration rates and their impacts in a green space in Brussels, Belgium", which is pretty much environmental geography. Remember, if your favourite type of geograpy is say, arid environments, and they're not near you, you have to work with what you're given. My topic was more biogeography than anything else, which is my least favourite type of phys. geog, but I agreed to do it anyway.
Next, you need to think about fieldwork. For human EEs, do you have a group of persons you could give questionnaires to? Are there important officials around to help give you information? Do you live in a country where you don't speak the language, and might need assistance from a friend or a family member? For physical EEs, do you have access to apparatus that would be suitable for an experiment? Are you
allowed to experiment there? What days would you have to do your fieldwork on, taking into consideration the ever-so-important climate?
Then, consider the available secondary info. Where will you get demographic/climatic statistics from? Are there any websites which could help you with this?
Taking into account your available places of study, your general area of study, your organisation of fieldwork (i.e primary data) and secondary data, you can then form your research question.
Remember that your EE is going to be quite scientific in its approach, so if you are uncomfortable with lab-type work, I would advise against doing a geog. EE.
